Orbital Myiasis

To present a case of massive orbital myiasis. An 87-year-old debilitated woman suffering from left ocular pain of four days' duration presented with a severely necrotized left orbit and several attached live larvae. The upper and lower eyelids and the eyeball were completely destroyed. She had history of eyelid surgery in the same eye due to a skin lesion, apparently some type of skin cancer, 15 years before. The larvae were identified as Chrysomya bezziana [Diptera: Calliphoridae] or old world screwworm fly. Infestation of ocular and orbital tissues by fly larvae [ophthalmomyiasis] progresses rapidly and can completely destroy orbital tissues within days, especially in patients with poor general health. Treatment consists of removal of the larvae and surgical debridement

Incidence of Helicobacter pylori in central serous chorioretinopathy: a case control study

Helicobacter pylori infection is one of the most common infections worldwide. Central serous chorioretinopathy [CSCR] is a serous macular detachment that usually affects young people. The aetiopathogenesis of the disease is still not completely understood. Recently, an interesting association has been observed between this disease and the H. pylori infection. This study was conducted to investigate a possible association between H. pylori infection and CSCR. A prospective study was performed and we evaluated a total of 54 CSCR patients [48 males and 6 females, median age 35.7 years], and a control group of 59 patients [25 women, 34 males; mean age 42.6 +/- 11 years] who referred to gastroenterology department of Imam Hospital, Ahvaz Jundishapur University of Medical Sciences, were studied. Central serous chorioretinopathy was diagnosed on the basis of findings in ophthalmic examinations and confirmed by fluorescein angiogram. All patients underwent a [13]C-urea breath test [UBT] and serum IgG anti-bodies to H. pylori by enzyme-linked immunosorbent assay technique to detect H. pylori infection. Patients were defined as H. pylori infected if both tests were positive. The mean duration of symptoms before diagnosis was 10.5 +/- 4.5 days. Overall no statistically significant difference was found between left and right eyes, bilaterally was in 5 patients [9.2%]. The incidence of H. pylori infection was 68.5% in CSCR patients and 65% in control subjects [p=0.64]. These results indicate that the prevalence of H. pylori infection is not higher in patients with CSCR than in controls. Further large studies will be required to determine the role of H. pylori infection in patients with CSCR

Comparison of Standard and undercorrected surgical methods for treating partially accommodative esotropia / 国际眼科杂志(Guoji Yanke Zazhi)

·AIM: To evaluate the efficacy of standard and undercorrected surgical methods in patients with partially accommodative esotropia (PAET).·METHODS: Twenty-five patients with PAET and normal accommodative convergence/accommodation ( AC/A )were divided into two groups for alternate surgical plan including standard method (13 patients) and under-corrected method (12 patients) in a randomized fashion.Standard method is based on measured deviation through full hyperopic correction at distant target and was performed by Parks scheme. Undercorrected method criteria is 20% lower than standard. All patients underwent symmetrical bilateral medial rectus recessions (BMR), and all of them were followed for 6 months.·RESULTS: Six months after operation, surgical success (defined as tropia =s 8A at distant and near fixation through full hyperopic correction) was 46% in standard group and 91% in undercorrected group. Overcorrection were observed 54% in standard group and 9% in undercorrected group (P＜0.05). There was no residual esotropia. There was no correlation between surgical success rate or overcorrection rate and age, mean of preoperative spherical equivalent or preoperative eye deviation.·CONCLUSION: Undercorrected BMR surgery has a lower overcorrection rate and higher surgical success rate than standard surgery in patients with PAET and normal AC/A.
